Structural perspective on Fine Tuning

Recently, during the debate prep on Thursday, Tim used an objection to things with beginnings needing causes in the property of quantum fields to generate particle-antiparticle pairs seemingly at random with no source. While the obvious response to this is to point out that just because we don't observe the cause doesn't mean there isn't one, and this effect is still contingent on the properties of the fields themselves. However, this led me to think about this effect and how the naturalist would use this process to explain where stuff comes from. A few important notes. 1. Both the Theist and Atheist are following Ockham's Razor, so the theory with the most post hoc assumptions is worse. 2. In physics it is a well-known principle that the source of the vast majority of physical laws comes from symmetries in the universe. 3. One common theory for the Big Bang is that the massive energy condensed into particle anti particle pairs in a process called creation or pair production. 4. The way this process doesn't violate the conservation of energy on normal scales is that the particles and antiparticles annihilate each other.

One might ask if these particles always annihilate each other how could the universe come about. The answer is this: In our universe where basically all of the fundamental laws of physics are derived from symmetry we have one absolutely necessary violation of this called CP violation. This causes the decays of Kaons to slightly favor matter to antimatter. The physics itself is not as important as the asymmetry. If the naturalist is to attempt to impose a simple mechanism for the structure of the laws then they would be most reasonable to choose symmetry as this mechanism. To account for this effect they would also need to create an arbitrary limit to this mechanism and establish an asymmetry. This shows that not only are the constants (like the tuning pegs on a guitar) are finely tuned for life and existence, but the underlying structure (the guitar itself) is also finely tuned.
